 If your son is failing courses in school, or performing poorly on sports teams, he may be involved in a hacking group, such as the infamous "Otaku" hacker association. Excessive time spent on the computer, communicating with his fellow hackers may cause temporary damage to the eyes and brain, from the electromagnetic radiation. This will cause his marks to slip dramatically, particularly in difficult subjects such as Math, and Chemistry. In extreme cases, over-exposure to computer radiation can cause schizophrenia, meningitis and other psychological diseases. Also, the reduction in exercise may cause him to lose muscle mass, and even to start gaining weight. For the sake of your child's mental and physical health, you must put a stop to his hacking, and limit his computer time drastically.
 
 I encourage all parents to read through this guide carefully. Your child's future may depend upon it. Hacking is an illegal and dangerous activity, that may land your child in prison, and tear your family apart. It cannot be taken too seriously.
